Description de produit
Black Anodized Aluminum Extruded LED Heat Sink
This is a mainstream passive cooling model, which can also be fitted with a fan to form an active cooling module. It is specially designed for high‑power LED lighting fixtures.
Anodized black aluminum extrusion extruded heat sink has the characteristics of good heat dissipation performance and good energy saving effect.Material: Aluminum 6063-T6Product dimension: Can be customizedProduct weight: 0.5kgFeature: Lower costs and higher cooling dissipationSurface treatment: Anodized blackHeat conducting power: 50 WProduct Technology: Extrusion and anodizing
I. Base Material & Processing Technology
- Substrate: Mainstream 6063‑T5 aluminum alloy with thermal conductivity of approx. 237 W/(m·K). Extruded in one piece, featuring dense and uniform fins, stable structure and lightweight design.
- Forming Method: Aluminum extrusion. Multi‑fin structure formed in a single process, offering large heat dissipation area, low cost and unlimited cutting length.
- Surface Treatment: Black anodizing (sulfuric acid anodizing). Film thickness: 10–15 μm for indoor use, thickened to 20–25 μm for outdoor use. Matte black finish, fade‑proof and chip‑resistant.
II. Core Advantages (vs. Ordinary Aluminum Heat Sinks)
- Superior Heat Dissipation: The black anodized layer greatly improves infrared emissivity, delivering 15%–20% higher heat dissipation efficiency than bare aluminum, with significantly enhanced natural convection performance.
- Durable Protection: The dense oxide film isolates air and moisture, providing resistance to corrosion, salt spray and UV rays. No oxidation or rusting for 5–10 years outdoors; high surface hardness for wear and scratch resistance.
- Electrical Safety: Insulating oxide film prevents short circuits of LED aluminum PCBs, suitable for high‑voltage and high‑power lamps.
- Premium Appearance: Matte pure black finish matches the industrial‑style look of high‑bay lights, flood lights, plant grow lights and stage lights.
- Wide Compatibility: Can be equipped with DC cooling fans to form the fan‑assisted active cooling module you previously required, compatible with 50–300 W high‑power LEDs.
III. Structural Types (Common for LEDs)
- Straight Dense‑Fin Type: Long extruded profiles for linear flood lights and wall wash lights.
- Sunflower / Round Extruded Type: For high‑power bulb lights, high‑bay lights and COB LEDs.
- Square Comb‑Fin Type: Widely used for high‑power integrated COB light sources, most commonly paired with fans.
IV. Application Scenarios
High‑power LED flood lights, high‑bay lights, stadium lights, tunnel lights
Plant grow lights, UV curing lights, stage PAR lights
Outdoor industrial lighting, security fill lights, energy storage power supply heat dissipation
Can be matched with 12 V / 24 V silent fans for high‑power and enclosed‑environment applications.
V. Key Selection Parameters
- Fins: Higher and denser fins mean better heat dissipation. Fin spacing of 8–12 mm is optimal to balance heat dissipation and ventilation.
- Anodizing: 10 μm for indoor use; thickened anodizing ≥20 μm for outdoor or coastal environments.
- Fan Matching: For high‑power applications, directly adopt integrated extruded heat sink‑fan solutions for lower thermal resistance and better temperature control.
